## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

MADE SHARP LEFT TURN AFTER TAKEOFF AND CRASHED SOUTH OF RUNWAY. (.4)THE PILOT/OWNER OF THE AIRPLANE AND A PASSENGER DEPARTED ON A LOCAL FLIGHT. AFTER TAKEOFF FROM RUNWAY 33L, AT 200 TO 300 FEET ABOVE THE GROUND, THE ENGINE LOST POWER. THE PILOT INITIATED A LEFT TURN BACK TO THE AIRPORT, AND MADE A WHEELS-UP LANDING ON THE APPROACH END OF RUNWAY 10, HEADING IN A WESTERLY DIRECTION. THE AIRPLANE THEN SLID ONTO THE GRASS BETWEEN THE TAXIWAY AND RUNWAY. EXAMINATION OF THE AIRPLANE BY AN FAA INSPECTOR REVEALED FUEL IN THE AIRPLANE'S FUEL TANKS, LINES, AND FILTER. EXAMINATION OF THE ENGINE REVEALED VALVE TRAIN CONTINUITY, COMPRESSION IN ALL CYLINDERS, AND SPARK FROM THE MAGNETOS. THE AIRPLANE HAD NOT BEEN FLOWN FOR ABOUT 1 MONTH, AND WAS REFUELED JUST PRIOR TO THE FLIGHT. THE PILOT WAS ALSO AN FAA CERTIFIED MECHANIC. HE STATED THAT HE HAD MADE A LOG BOOK ENTRY OF THE AIRPLANE'S ANNUAL INSPECTION AND SIGNED IT OFF THE EVENING AFTER THE ACCIDENT, BUT HE COULD NOT RECALL WHEN THE INSPECTION WAS ACTUALLY COMPLETED.
